INGOT-MOLD.

Specification of Letters Patent.

Patented Get. 30, 191?.

Application filed .Tune 12, 1917. Serial No. 174,403.

To all whom it may concern Be it known that I, JOSEPH SC TT, a citizen of the United States, residing at Charles ton, in the county of Kanawha and State of lVest Virginia, have invented new and useful Improvements in Ingot-Molds, ofwhich the'following is a specification.

This invention relates to ingot molds and it has Special reference to that class of molds which are made of two parts adapted to be.

separated for the purpose of releasing the ingot, said parts being joined together by means of links.

The invention has for its object to simplify and improve the construction of a separable ingot mold.

A further object of the invention is to produce a simple and improved joint for the parts of the mold, said joint being so constructed and arranged that it will not be liable to become warped when the mold is in use.

With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claim.

In the accompanying drawing has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claim may be resorted to when desired.

In the drawing,

Figure 1 is a view in side elevation of the improved mold showing the same 1n positlon for use.

Fig. 2 is a side elevation showing one part of the mold lifted in position to release an ingot.

'Fig. 3 is a vertical sectional view.

Fig. 4 is a top plan view.

Fig. 5 is a horizontal sectional view.

Corresponding parts in the several figures are denoted by like characters of reference.

The two parts, halves or sections of the improved ingot mold are designated respectively by A and B and said sections are provided on their opposite side faces with studs or pivot members 15 on which connecting links 16 are mounted, said links bemg obliquely disposed whenv the sections are the mold by means of the customary tackle provided for the purpose. It will be seen that by applying upward stress to the section A, the said section will be moved outward and upward with respect to its mate, as seen in Fig. 2, thus releasing the ingot. By applying upward stress to the section B, the entire mold may be lifted, the section A remaining gravitationally in contacting en-- gagement with itsmate. The inner walls of the two sections are tapered upwardly and downwardly s seen at 19, 20, in Fig. 3, thereby producing an ingot with tapered ends which is found convenient and useful in avoiding wastage when the ingot is to be rolled.

The meeting faces of the two sections of the mold are formed with a lap-joint, as best seen in Figs. 4 and 5, said joint being composed,of Overlapping tongues 21 and 22 formed on the sections A and B respectively, and said tongues having obliquely disposed meeting faces 23 and fiat meeting faces 24, 25, said flat meeting faces being disposed in parallel relation to each other and substantially at right angles with respect to the walls of the respective sections A and B. It is to be particularly observed that the obliquely disposed faces of the overlapping tongues are to be disposed at a materially greater distance from the inner than from the outer faces of the mold sections as will be clearly seen in Figs. 4 and 5. By this arrangement the oblique meeting faces of the joint are less liable to become warped or injured by the heat of the molten metal than if said meeting faces were disposed midway between the inner and outer faces, relatively near the inner faces of the mold sections.

This is regarded as an important and valuable feature of the present invention, it having been found that molds embodying this structural feature, are much longer lived than molds having joints composed of interengaging grooves and tongues as is customary at the present time.

My improved ingot mold, as will be seen from the foregoing description, is simple in construction and capable of being produced at an expense not exceeding that of molds as originally made. It may be convenient to handle and manipulate, and the joint constructed as herein described is simple and thoroughly efiectire, particularly in connection with the links whereby the sections of the mold are connected together. It will be understood that when the mold is placed on the floor adjacent to a furnace for the purpose of receiving a charge of molten metal, the section A will gravitate downwardly and at the same time the said section will be drawn by the action of the links 16 in the direction of the mating section B, the section A being free to sink in the sand which forms the floor until the oblique meeting faces of the lap-joint are in close engagement with each other. It has been found that a much tighter joint will thus be formed between the mold sections than where a tongue and groove joint is employed, at the same time dispensing with the use of screws,

ne -races wedges or other means for forcing the mold sections in the direction of each other.

1 claim An ingot mold consisting of two sections having a lap-joint comprising two overlap ping tongues having obliquely disposed meeting faces, said meeting faces being disposed at a materially greater distance from the inner than from the outer faces of the mold sections, said mold sections being pro vided on opposite side faces with pivot studs and with connecting links engaging said studs said connecting links being obliquely disposed when the sections are placed with their meeting faces in contacting engagement.

In testimony whereof I affix my signature.
